Militants have launched a bomb and gun attack on a mosque in Egypt's North Sinai province, killing 235 people, state media say.
The al-Rawda mosque in the town of Bir al-Abed was targeted during Friday prayers.
No group has yet claimed the attack, but militants affiliated with so-called Islamic State (IS) have been responsible for scores of deadly attacks in the province.
They usually target security forces and Christian churches, and the bloody attack on a mosque associated with Sufi Muslims has shocked Egypt.

Witnesses said dozens of gunmen arrived in off-road vehicles and bombed the packed mosque before opening fire on worshippers as they tried to flee.
The assailants are reported to have set parked vehicles on fire in the vicinity to block off access to the mosque.
Pictures from the scene show rows of bloodied victims inside the mosque. At least 100 people were wounded, reports say, overwhelming hospitals.
It is the deadliest militant attack in modern Egyptian history. Bir al-Abed is about 130 miles (211km) from Cairo.
Followers of Sufism, a mystical branch of Sunni Islam, regularly gathered at the mosque.
The victim of the mosque attack also included military conscripts.
